War on Christmas

Five months into the first World War, troops along the Western front took a Christmas Eve break from fighting to sing carols to one another across the battlefield. The following morning, German soldiers emerged from the trenches and began to approach Allied troops while calling out "Merry Christmas" in English. Luckily, it wasn't a trick; dozens of British fighters came out to greet them and shake hands, some even exchanging cigarettes as gifts. Later dubbed the Christmas Truce of 1914, it was one of the last examples of wartime chivalry.
